摘要： An apparatus is disclosed for automatically casting separately molded bowl and rim members and then connecting them together while both are in an upside down position. During the connection of the rim to the bowl, the bowl is preferably supported on two opposing sides by the mold. These procedures reduce deformation of the cast bowl while it is still in a “greenware” condition.

摘要： In an improved method for the production of slabs of ceramic material the starting mixture is enclosed between two sheets of cardboard or paperboard, subjected to vibrating compression under vacuum. The aboard or paperboard being thick enough to absorb the excess mixture water prior to the transfer to the subsequent drying and firing stages, said sheets of paperboard being removed before said drying stage, so that the rough-formed slab is dried resting solely on a porous fabric or felt, and baking is performed while keeping the dried rough-formed slab in contact with the oven surface solely by means of a temporary protective layer of refractory material (engobe).

摘要： A dry pressing and slip casting process is provided for the manufacture of glass-ceramic components of the type used in sensors. Both process on starts with a powder composition of SiO2 (42-59 wt. %), Al2O3 (17-35 wt. %), MgO (2-25 wt. %) and also BaO (0-20 wt. %), TiO2 (0-12 wt. %), ZnO (0-10 wt. %), CaO (0-10 wt. %), B2O3 (0-5 wt %), P2O5 (0-5 wt. %), ZrO2 (0-5 wt. %), alkali oxides such as K2O, Na2O (0-3 wt. %) and other small amounts (0-1 wt. %) of additives such as Fe2O3, As2O3. Fe2O3, V2O5, As2O3. Some of the ingredients (e.g. Mg, Ba, Ca) can also be present in the form of fluoride, e.g., MgF2, BaF2, CaF2, to up to 10 wt. %. Additional ceramic additives up to 30 wt. %, which are as second phase (e.g., Al2O3, Y2O3 doped ZrO2, SiO2, mullite, zircon, carbides, nitrides, and a combination of the above), are not part of the glass composition, but are introduced to enhance both the mechanical strength and toughness and to further modify the coefficient of thermal expansion. In the dry pressing process the powder is milled, blended with a binder and then subjected to a drying/granulation process. A die cavity of a desired shape is then filled with the powder. Pressure is then applied to die for a period of time. After the pressure is removed, the green ceramic part is ejected and then sintered to become a finished ceramic cover or header. In the slip casting process, the powder is milled and dispersed in a water. The slip is then poured or pumped into a permeable casting mold of a desired shape made of Gypsum. When either the liquid has been completely sucked away by the mold or the desired depositing thickness has been reached, the cast green ceramic part is removed from the mold, dried and then sintered into a finished ceramic cover or header.

摘要： A method for forming a ceramic part with an internal structure includes aqueous slip-casting and a polystyrene foam insert. An aqueous slurry is poured over the insert to form a green body. The insert is shaped to produce the desired internal structure upon being encased by the slurry. The insert is then removed from the green body by dissolving it in trichloroethylene. Because the polystyrene foam does not expand when exposed to trichloroethylene and rapidly dissolves, build up of shrinkage stress in the green body is avoided. The green body is then sintered to produce the ceramic part with an internal structure.
摘要翻译： 用于形成具有内部结构的陶瓷部件的方法包括水性滑移铸造和聚苯乙烯泡沫插入件。 将水性浆液倒入插入物上以形成生坯。 嵌件被成形为在被浆料包裹时产生期望的内部结构。 然后通过将其溶解在三氯乙烯中，将生物体从生坯中除去。 由于聚苯乙烯泡沫在暴露于三氯乙烯时不会膨胀并迅速溶解，因此可以避免在生坯体内形成收缩应力。 然后将生坯烧结以产生具有内部结构的陶瓷部件。
